Description

We introduced system_distributed keyspace in C* 2.2 so that we can save the repair histories and ancestors to a system keyspace (due to CASSANDRA-5839). However, looks like it's hard-coding the replication factor to 3, according to this line:

https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/repair/SystemDistributedKeyspace.java#L103

This may confuse some query operations against this keyspace.
